Imagine of amazon quietly buys all the bitcoins from mt gox committee and then start accepting bitcoin as currency! If this possible? if yes, what flaws would it have?
[Edit : you are missing the FROM MTGOX part! I do not mean buy every existing coin in the world]
I think if ever amazon bought all the bitcoin it would just make the btc market dead or maybe best to be stable. Holding all bitcoin would make its market freeze and may drop its value from where it started, plus I think satoshi design bitcoin not to be controlled by a single entity or corporation though I just don't know its technicalities.
